Under warm 2700K interior light Koi is virtually unchanged; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 0.9), so it is a lighting-stable choice.

Against white it measures 3.68:1 and against black 5.7:1, so black text is the stronger pairing. That pairing passes WCAG AA for body text.
One color explored: close hues with real lightness and chroma structure, so the palette is the anchor through value rather than a set of colors.
#ffd8ca · #ff9d78 · #d2663b · #b04c23 · #822c00 · #4f1600
The anchor's neighbours on the wheel — everything shares an undertone, so the chord carries color without anything having to be muted to get along.
#dba355 · #d88540 · #d2663b · #bb524d · #a14257 · #85365b
The mid-gap pairing — sage and mustard, terracotta and olive. A foil rotated 40–65° toward warm or cool: too far to be kin, too near to argue, carried by temperature and a deliberate value offset.
#b8a872 · #d2663b · #a74f2c · #614f00 · #5f1d00 · #251c00
One deliberately opposed voice — a single restrained counterpoint across the wheel, or temperature against temperature where the anchor is too muted to carry a loud opposite.
#00d1ff · #d2663b · #806156 · #6f3a26 · #4c1f0d · #270a02
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#e4f5fc · #b6a097 · #d2663b · #657276 · #3e2820 · #000305
This color as a ground rather than a subject — its own restraint held across a narrow value band, carrying one saturated voice from the opposite temperature.
#e7f4f9 · #beced3 · #91a3a9 · #162e35 · #000b12 · #d2663b
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#dbdab5 · #44d5e2 · #d2663b · #9b657c · #314050 · #04110c
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#b8e3d2 · #6bada8 · #d2663b · #446279 · #323c59 · #20050e
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#d9fce8 · #56bc8d · #d2663b · #6361c2 · #281e6a · #000602
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#C47050 · #B67861 · #A77F71
Its chroma is high enough to carry accents, calls to action, and focal moments; large fields of it will dominate a composition. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
